Ammonia oxidation, nitrite oxidation, and nitrate reduction rates from cruises AT15-61 and MV1104 Dataset Description: Methods and Sampling: <p>Seawater samples were collected on R/V Atlantis (AT15-61) cruise in Jan-Feb 2010 and on R/V Melville (MV1104) cruise in Mar-Apr 2011.&nbsp;&nbsp;Water samples were collected at discrete depths using Niskin bottle type rosette samplers equipped with either 24&nbsp;bottles (10L), or 12 bottles (20L), and an SBE9plus conductivity-temperature-depth (CTD) sensor package (SeaBird Electronics, Bellevue, WA).&nbsp; Water for rate incubations was collected into 160 mL glass serum bottles (AT15-61) or 500 mL Tedlar sampling bags (MV1104).&nbsp; See below in&nbsp;Processing Description for further details.</p>
<p>Ammonia and nitrite oxidation rates were determined using&nbsp;<sup>15</sup>N tracer additions. Full methods can be found in the manuscript Santoro et al. (submitted). As described below, incubation methods varied slightly between the first and second cruises.</p>
<p>In Year 1 (2010), rates were determined at four depths at all six stations. Incubations were conducted in 160 mL glass serum vials. Six serum bottles were filled and sealed from each incubation depth, spiked with&nbsp;<sup>15</sup>N tracer (100-200 nM&nbsp;<sup>15</sup>NH<sub>4</sub>Cl or Na<sup>15</sup>NO<sub>2</sub><sup>-</sup>), and incubated in flowing seawater incubators screened to mimic the&nbsp;<em>in situ</em>&nbsp;light environment (euphotic zone samples) or temperature controlled chambers (sub-euphotic zone). Duplicate bottles were sacrificed at timepoints of 0, 12, and 24 h from each incubation depth, 0.2 µm syringe-filtered into a 60 mL HDPE bottle, and frozen at -20ºC.</p>
<p>In Year 2 (2011), rates were determined at six depths at five stations. No rates were determined at Stn 5 in Year 2. Incubations were conducted in 500 mL Tedlar bags. Duplicate incubation bags per treatment were filled from the Niskin bottles using silicone tubing, and&nbsp;<sup>15</sup>N tracer (200 nM&nbsp;<sup>15</sup>NH<sub>4</sub>Cl or Na<sup>15</sup>NO<sub>2</sub>) was added via the septum injection port. As in the previous year, bags were incubated at as close to&nbsp;<em>in situ</em>&nbsp;light and temperature as possible. At timepoints of 0, 12, 24, and 36 h, 50 mL samples were drawn from each bag through the three-way sampling port using a 60 mL syringe. At each timepoint, incubation water was 0.2 µm syringe filtered into a 60 mL HDPE bottle tripled rinsed with sample, and frozen at -20ºC.</p>
<p>Frozen samples were transported frozen to the laboratory, thawed, and prepared for&nbsp;<sup>15</sup>N<sub>NO2+NO3</sub>&nbsp;analysis using the ‘denitrifier method’ (Sigman<em>&nbsp;et al.</em>, 2001). For nitrite oxidation rate samples, the added&nbsp;<sup>15</sup>NO<sub>2</sub><sup>-</sup>&nbsp;tracer was removed using sulfamic acid addition and subsequent neutralization with NaOH (Granger<em>&nbsp;et al.</em>, 2006) prior to sample preparation and analysis. For 2010 samples, where only three timepoints were taken, rates were calculated using the linear fitting method of Dugdale and Goering (Dugdale and Goering, 1967). For 2011, where four timepoints were taken, rates were calculated using a least squares fitting approach that accounts for changes in&nbsp;<sup>15</sup>N<sub>NO2+NO3</sub>&nbsp;from co-occurring nitrate uptake (Santoro<em>&nbsp;et al.</em>, 2010 and attached analysis files).</p>
<p>Nitrate reduction rates to nitrite were determined in Year 2 using&nbsp;<sup>15</sup>NO<sub>3</sub><sup>-</sup>&nbsp;tracer additions (&gt;98 atm% Na<sup>15</sup>NO<sub>3</sub>).&nbsp;<sup>15</sup>NO<sub>3</sub>- incubations were only conducted in the euphotic zone (three depths). Tedlar incubation bags were prepared and filled as above, and 200 or 400 nM (final concentration) of Na<sup>15</sup>NO<sub>3</sub>&nbsp;was added to each bag using a plastic syringe. Timepoints were sampled and preserved as for the nitrification rate incubations above. In the laboratory, samples were prepared for&nbsp;<sup>15</sup>N<sub>NO2</sub>&nbsp;determination using the ‘azide method’ (McIlvin and Altabet, 2005). Following azide conversion to N<sub>2</sub>O, samples and standards (N23, N7373, and N10219; (Casciotti<em>&nbsp;et al.</em>, 2007) were analyzed by IRMS and rates were calculated as described above.</p>
<p>Light inhibition experiments were conducted in Year 2 to test the effect of sunlight on ammonia oxidation, nitrite oxidation, and nitrate reduction. These incubations were conducted at the two shallowest incubation depths, approximating the 1% and 10% light depths at Stations 7, 9, and 11. For these experiments, one set of duplicate incubation bottles for each rate type was incubated at ambient light (bottles 1 and 2 in the data file) and the other in the dark (bottles 3 and 4 in the data file). Tracer addition, subsampling, analysis, and rate calculations were as described above.</p>

Expression of Microbial Nitrification in the Stable Isotopic Systematics of Oceanic Nitrite and Nitrate

Expression of Microbial Nitrification in the Stable Isotopic Systematics of Oceanic Nitrite and Nitrate
<p><em>Description from NSF award abstract:</em><br />
Closing the marine budgets of nitrate and nitrous oxide are central goals for researchers interested in nutrient-driven changes in primary productivity and climate change. With the implementation of new methods for oxygen isotopic analysis of seawater nitrate, it will be possible to construct a budget for nitrate based on its oxygen isotopic distribution that is complementary to nitrogen isotope budgets. Before we can effectively use oxygen isotopes in nitrate to inform the current understanding of the marine nitrogen cycle, we must first understand how different processes that produce (nitrification) and consume (assimilation, denitrification) nitrate affect its oxygen isotopic signature.</p>
<p>In this study, researchers at the Woods Hole Oceanographic Institution will provide a quantitative assessment of the oxygen isotopic systematics of nitrification in the field and thus fill a key gap in our understanding of 18O variations in nitrate, nitrite, and nitrous oxide. The primary goal is to develop a quantitative prediction of the oxygen isotopic signatures of nitrite and nitrate produced during nitrification in the sea. The researchers hypothesize that oxygen isotopic fractionation during nitrification is the primary factor setting the 18O values of newly produced nitrate and nitrite. Secondly, they hypothesize that oxygen atom exchange is low where ammonia oxidation and nitrite oxidation are tightly coupled, but may increase in regions with nitrite accumulation, such as in the primary and secondary nitrite maxima. They will test these hypotheses with a series of targeted laboratory and field experiments, as well as with measurements of nitrite and nitrate isotopic distributions extending through the euphotic zone, primary nitrite maximum, and secondary nitrite maximum of the Eastern Tropical South Pacific. The results of these experiments are expected to provide fundamental information required for the interpretation of 18O isotopic signatures in nitrite, nitrate, and N2O in the context of underlying microbial processes. A better understanding of these features and the processes involved is important for quantifying new production, controls on the N budget, and N2O production in the ocean -- which should lead to a better understanding of the direct and indirect interactions among the nitrogen cycle, marine chemistry, and climate.</p>

The SBE 9 is the Underwater Unit and is most often combined with the SBE 11 Deck Unit (for real-time readout using conductive wire) when deployed from a research vessel. The combination of the SBE 9 and SBE 11 is called a SBE 911. The SBE 9 uses Sea-Bird's standard modular temperature and conductivity sensors (SBE 3 and SBE 4). The SBE 9 CTD can be configured with auxiliary sensors to measure other parameters including dissolved oxygen, pH, turbidity, fluorometer, altimeter, etc.). Note that in most cases, it is more accurate to specify SBE 911 than SBE 9 since it is likely a SBE 11 deck unit was used. more information from Sea-Bird Electronics Community Standard Description: http://vocab.nerc.ac.uk/collection/L05/current/130/
